Structural And Geochemical Analyses Of Disseminated-Gold Deposits, Bald Mountain-Alligator Ridge District, Nevada: Insights Into Fault-Zone Architecture And Its Effect On Mineralization, K. Jill Hammond

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Structural and geochemical analyses of the Top and Casino deposits, Bald Mountain-Alligator Ridge district, Nevada, were conducted to determine how structures affected gold deposition in Carlin-type deposit s. We also examined how permeability changed over time in a fault that cuts siltstone-dominated sedimentary rocks. The association of gold and related arsenic with faults at the margins of a Jurassic pluton and sedimentary rocks suggests that ore fluids migrated along faults and fracture s. Permeability of the faults changed over time within the Casino deposit, where the ore-controlling fault was a distributed conduit in the early stages of mineralization but a …

The Efficacy Of Plant Residue Degradation Products On Phosphorus, Iron, Iodine, And Fluorine Bioavailability To Plants, Cheryl L. Mackowiak

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Plant and animal wastes degrade in soils to form relatively stable humified compounds, which form ion complexes that affect the bioavailability of elements in the soil solution. Hydroponic studies with wheat and rice were conducted to characterize the effect of humic acid (HA) on phosphorus (P), iron (Fe), fluorine (F), and iodine (I) bioavailability. Ferrihydrite [Fe(OH)₃] precipitation was greater on root surfaces without HA or synthetic chelates. Oxides such as ferrihydrite strongly adsorb P and provide exchange sites for metals. HA reduced this precipitate and increased P and Fe uptake.

Humic acid had no effect on F toxicity …

A Longitudinal Study Of Attention-Deficit/Hyperactivity Disorder Symptoms In Preschool-Age Children, Jessica Nicole Greenson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Attention-deficit hyperactivity disorder (ADHD) is among the most common reasons for referral to children's mental health clinics, with an estimated prevalence of 3% to 5% in the general population of school-age children. Children who exhibit the requisite behaviors may obtain a diagnosis of ADHD at any age; however, symptom onset must occur before age 7 and persist for at least 6 months. Despite these temporal requirements for diagnosis, little empirical information about the manifestation and stability of ADHD symptoms in preschool children exists. This study provides information about the initial presence and stability over one academic year of ADHD behaviors …

Effectiveness Of Earthen Escape Ramps In Reducing Big Game Mortality In Utah, Mary L. Hammer

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

One-way escape gates and earthen escape ramps are structures used to enable deer to exit the highway right-of-way along fenced roads. I compared the use of one-way escape gates and earthen escape ramps by mule deer on two highways in Utah to determine if deer exhibited a preference for either structure. Results showed that earthen escape ramps were used by mule deer 8-11 times more frequently than one-way gates. Highway mortality data suggest that the installation of the escape ramps likely reduced mortality of mule deer in both study locations, because we could not attribute reductions in mortality to decreased …

Intensification In A Risky Environment: The Case Of Improving Private Grazing Land For Beef Production In Utah, Louise D. Sainsbury

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Utah ranchers commonly face risks to their livelihoods. The objective of this work was to determine if ranchers could make profitable improvements to private land forage given the combined threat of low beef prices, drought, and possible loss of public grazing.

We used linear programming (LINDO) to identify the most profitable solutions for private land investment with an 11-year simulation. Operations were divided into small, medium, and large size classes. Various forage improvements and public permits were options. Two phases of a beef price cycle (peak and trough) and 2 precipitation patterns (wet and drought) were combined as joint favorable …

Relationship Between Cag Repeats Of The N Terminal Region Of The Androgen Receptor And Body Shape, Michael John Wen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Effects Of Sediment Upon Benthic Macroinvertebrates In Forested Northern Appalachian Streams, Michael Douglas Kaller

Graduate Theses, Dissertations, and Problem Reports (ETD)

Excess fine sediment negatively influences the fauna of North American streams. With the current emphasis on multiple-use forests, the question is not whether fine sediment is detrimental, but what is the threshold of fine sediment that is tolerable?;To determine a threshold tolerance of fine sediment, a two-part project investigated the influence of fine sediment upon benthic macroinvertebrates. The first part encompassed two experiments in sediment manipulation in 1999 and 2000. The experiments tested benthic macroinvertebrate metric sensitivity to a range of fine sediment treatments. The second part involved four seasonal surveys of seven streams to determine the threshold amount of …

Effects Of Type-I Collagen Fractional Composition And Pyridinium Crosslink Content On Cortical Bone Strength In The Human Femur, Michael Blair Rice

Graduate Theses, Dissertations, and Problem Reports (ETD)

Type-I collagen's role in the formation of bone and its inherent strength have been well documented by studies in genetic diseases such as Osteogenesis Imperfecta. Type-I collagen's role in healthy bone, and the changes that occur to collagen during aging, which may eventually lead to osteoporosis, is less understood. Changes that may occur include differences in collagen production and in its processing such as differences in glycosylation and the hydroxylation of specific amino acid residues. Changes in the reducible and non-reducible crosslink content, or changes in the ratio of crosslinks to total collagen may also occur. The present study investigated …

Pattern Recognition In Software Engineering Trend Adapting, Dapeng Chen

Graduate Theses, Dissertations, and Problem Reports (ETD)

Whether and when to adapt to certain software engineering trends are difficult questions to be answered by many decision-makers. The main reasons are due to the fact that evolution of software engineering trends itself is determined by various factors, many of which come from the fields outside of the software technology, thus hard to predict. So it is even harder to estimate the cost and benefit when adapting to certain trends. This paper is intended to study ways to decrease the risk involved in such decision making processes, by developing a pattern from past software engineering trends. While the pattern …

The Indian Child Welfare Act; An Acknowledgement Of Sovereignty In The Best Interests Of The Child, Cedric Ian Hay

Student Thesis Honors (1996-2008)

In part II of this paper the social, legislative, and judicial histories that lead to the situation that the ICWA was designed to correct will be discussed. There was substantial testimony before Congress during the creation of the act. The resulting Act is an express affirmation that the United States policy of assimilation and removal of Indian children from the tribes has been replaced with an acknowledgement of a tribe's sovereign interest in controlling the placement of its most precious resource, its children. Part III will examine the reaction of the states to the requirements imposed by ICWA. Adoption advocates …

A Hermeneutic Study: The Impacts Of The Harm Reduction Approach On Women Living In Abusive Relationships, Darla Segelstrom

Theses and Graduate Projects

Despite the number of services available to battered women, few focus on working with those who remain in the abusive relationships. The Harm Reduction approach is one geared towards working with women who have not yet made the decision to leave their abusive partner. This hermeneutic, interpretive study of women's narratives revealed that the harm reduction approach provided non-judgmental support, which was conducive to increasing women's overall awareness of themselves, their situation, and their options. It is recommended that social workers and other human service agencies recognize the complexity, individuality and strength in each battered woman they encounter, facilitate a …
